yea for 5 i was tossing up between b or c, i stayed with b so hopefuly its correct.
with question 9, i think the current went from R to P, which means the electrons go the other direction and hence a build up at R giving me the answer of C
i had 13 different, i got A, but i wasnt sure
the rest was cool

As for 9, my re3asoning was that eddy currents are formed in the thin conductor, so electrons would be concentrated around Q or S, but S was experiencing the most change in magnetic flux so more electrons would be concentrated there, due to the induced current, but I'm REALLY not sure hehe. I want the answer to it so bad xD

I think 5 is B. if u look at the universal law of gravitation, F decreases with increasing distance.
As for 9 i think it is A. using right hand rule and lenz's law, opposing force goes up and field is into the page...so positive current goes to the right and electrons are at in the opposite side at P..anyone agree?
